Tasks — Slim @suaveplan/currency-providers

Spec-completeness preflight (AGENTS.md §12a)

• Numbered checklist of every ### Requirement and #### Scenario drafted in specs/currency-providers/spec.md (10 requirements kept/added; see ./specs/currency-providers/spec.md).

Remove concrete provider modules

• Delete src/providers/ecb/
• Delete src/providers/fixer/
• Delete src/providers/open-exchange-rates/
• Delete src/providers/binance/
• Delete src/providers/coingecko/
• Delete src/providers/coinmarketcap/
• Delete src/providers/cryptocompare/
• Delete src/providers/kraken/
• Delete src/providers/virtual/
• Delete now-empty src/providers/ directory
• Drop the 9 ./providers/<name>/<name> subpath exports from package.json
• Drop @suaveplan/currency and @suaveplan/money from dependencies iff no remaining surface needs them — actually @suaveplan/currency stays (registry stores CurrencyProvider instances from that pkg) and @suaveplan/money drops (only the deleted VirtualCurrencyProvider used registerCurrency).

Add slim-core surface

• Add PROVIDER_NOT_REGISTERED + PROVIDER_ALREADY_REGISTERED codes to CURRENCY_PROVIDER_CODES (src/error-codes/error-codes.ts)
• Build src/registry/registry.ts — CurrencyProviderRegistry class with register / get / has / list / unregister
• Build src/registry/registry.md (sibling doc, ≥200 words)
• Build src/registry/registry.test.ts — covers every method, both registry error codes, list() sort determinism
• Build src/factory/factory.ts — defineCurrencyProvider factory
• Build src/factory/factory.md
• Build src/factory/factory.test.ts
• Build src/http/http.ts — httpRequest + composeAbortSignal
• Build src/http/http.md
• Build src/http/http.test.ts — happy path, HTTP_ERROR on non-2xx, header forwarding, caller-signal abort, timeout-signal abort, both signals abort, composeAbortSignal all four combinations
• Update src/error-codes/error-codes.test.ts to assert the two new codes and prove they are reachable from registry call sites
• Update src/index.ts — explicit named barrel with new exports + drop removed provider exports
• Update package.json exports map: 5 subpaths total (., ./error-codes/error-codes, ./types/configs, ./registry/registry, ./factory/factory, ./http/http)
• Update tests/dep-graph.test.ts to match the new subpath list (or delete the per-subpath assertions and replace with a check that every <feature>/index.ts is referenced from a subpath export)
• Update vite.config.ts external list (drop @suaveplan/money)

Documentation

• Update README.md Modules + Provider summary sections to describe the slim core (registry / factory / httpRequest / shared types) and link to the future sibling packages
• Confirm every .ts in src/ has a sibling .md (the §13 step-5 grep returns zero)

Pre-archive gates (AGENTS.md §13)

• Step 0 — spec reconciliation: every ### Requirement and **Verified by:** resolves to a real file + verbatim test name
• Step 1 — bunx turbo lint typecheck test --filter=@suaveplan/currency-providers and bun run check both green
• Step 2 — bunx turbo test:coverage --filter=@suaveplan/currency-providers reports 100/100/100/100 via istanbul
• Step 3 — bunx turbo build --filter=@suaveplan/currency-providers green
• Step 4 — banned-pattern grep returns zero
• Step 4a — barrel-shape grep returns zero
• Step 4b — test-runner-import grep returns zero
• Step 5 — missing-.md grep returns zero
• Step 6 — README present
• Step 7 — bare-version grep returns zero
• Step 8 — subpath-export count = 5 (matches feature module count)
• Step 9 — security-scan grep returns zero
• Step 10 — dependent sweep (bunx turbo test --filter=...@suaveplan/currency-providers)

Root-doc refresh (AGENTS.md §13b)

• Re-run bun scripts/folder-reorg/generate-manifest.ts to refresh MANIFEST.md
• Re-run bun scripts/generate-missing.ts to refresh MISSING.yml
• Update STATUS.md row for @suaveplan/currency-providers to describe the slim shape
• Update SUMMARY.md row for @suaveplan/currency-providers likewise
• bunx markdownlint-cli2 --fix across touched root + change files

Archive (AGENTS.md §14)

• Fold specs/currency-providers/spec.md into openspec/specs/currency-providers/spec.md (apply REMOVED + ADDED to the canonical spec landed by the 2026-05-17 change)
• Move openspec/changes/slim-currency-providers/ → openspec/archive/2026-05-17-slim-currency-providers/
